staging: Add framebuffer driver for XGI chipsets

This driver handles XG20, XG21, XG40, XG42 chipsets from XGI. They're
also known as Z7,Z9,Z11 chipsets. It's based on the SiS fb driver but
has been heavily modified by XGI to support their newer chipsets.

drivers/staging/xgifb/TODO

+This drivers still need a lot of work. I can list all cleanups to do but it's
+going to be long. So, I'm writing "cleanups" and not the list.
+
+Arnaud
+
+TODO:
+- clean ups
+- fix build warnings when module
+- sort out dup ids with SiS driver
+- remove useless/wrong/unused #ifdef/code/...
+- fix printk usages
+- get rid of non-linux related stuff
+
+Please send patches to:
